84 Mpg At What Speed

[jack akridge]

Any body have an idea what speed it get 84 MPG. I am thinking 55 MPH

 

[Jambe]

I believe I have read at 65 mph with the a/c on.

Could depend on the aero. For a long time I had assumed that faster always meant less fuel efficient until a pilot was explaining that due to the plane's aero(leer 31a) that it was more efficient at a moderate cruise than just above stall coming in for a landing.

I think EM will try to follow what the car mfgs. do. I googled it and found a car and driver article titled
The Truth About EPA City / Highway MPG Estimates
So, I think that is how EM will come up with 84 mpg
.

I will be very happy with 65 to 70 mpg.I avg 39.7 with my current car and that is up from the 17 mpg my pick up averaged. 84 would be great, but at this point may be a high estimate

Mine (in my mind's eye), with tweeks to the aero and engine, will be getting 100mpg at 70mph. And that's not even factoring in the 'hot air' that could be converted to energy emitted by myself.

I also remember (sorta) reading somewhere that it was at 65MPH. I suspect it will be based on the EPA auto rating as well. If that is the case I should see and actual 84. I looked up the rated milage on my current rides and I get above or within 1 MPG of the rated on 5 different cars and trucks with 4 different drivers(Son,Daughter,Wifey and myself). Measured over many tanks of gas, and got better than that before the "whisky"gas became the norm. I justified my decision on 75mpg , so 84 would be icing, I like icing....and pie too

Every vehicle has that certain sweet spot where it's most efficient. My 2000 Dodge Ram 1500 quad cab, long bed, 5.9L gas
gets it's best mileage and is happiest at 70+mph, go figure. My wife's 97 Dodge 2500 high top conversion likes 65 or thereabouts.
I've taken to running a bit of "Sta-bil" in each tank to help ward off the "Whisky Gas" meanies.
We check our mileage every time we go to see family in Florida, 6 to 8 times a year. I75 is our test track, we prefer to travel in the wee
hours, so we can run consistent speed for most of it. North Georgia to West Florida is no picnic any other time of day and I think the
temperature has a bit to do with the results.

Best MPG on my truck is at 65, once I hit 70 it sucks, car is 70 to 75. We usually test MPG going across Nebraska on I-80 on our way to northern Minnesota, nice flat road running at 75-80mph

Where in Northern Minnesota?, I'm from there.
